===Logical and shift===
The logical instructions consist of those for performing [[Bitwise operation|bitwise]] logical operations and [[conditional move]]s on the integer registers. The bitwise logical instructions perform [[Logical conjunction|AND]], [[Sheffer stroke|NAND]], [[Logical NOR|NOR]], [[Logical disjunction|OR]], [[XNOR]], and [[XOR]] between two registers or a register and literal. The conditional move instructions test a register as a signed quadword to zero and move if the specified condition is true. The specified conditions are equality, inequality, less than or equal to, less than, greater than or equal to, and greater than. The shift instructions perform [[Arithmetic shift|arithmetic right shift]], and [[Logical shift|logical left and right shifts]]. The shift amount is given by a register or literal. Logical and shift instructions use the integer operate instruction formats.
